I'm a size 10 and wasn't sure it would fit right. It hugs every curve without feeling tight. The waistband is firm but never painful. I wore it to pilates and got compliments the whole class.
-
Every legging I've tried rolls down mid-workout. This one stayed perfectly in place through a full 90-minute hot yoga session. The one-piece design is a total game changer. No adjusting, just moving.

I thought the scrunch was too trendy for my age but it looks elegant in person. Subtle enough to be classy, effective enough to actually lift. I feel confident whether I'm at the gym or grabbing coffee after.

Tip — When between two sizes, we recommend sizing down for maximum sculpting effect. Measurements are of the garment. For body measurements, add 2–4 cm to waist and hip.

I was skeptical about the sizing — totally wrong
I'm a size 10 and wasn't sure it would fit right. It hugs every curve without feeling tight. The waistband is firm but never painful. I wore it to pilates and got compliments the whole class.
-
Thought it would roll down like every other legging I own
Every legging I've tried rolls down mid-workout. This one stayed perfectly in place through a full 90-minute hot yoga session. The one-piece design is a total game changer. No adjusting, just moving.

Wasn't sure the scrunch butt thing was for me at 45
I thought the scrunch was too trendy for my age but it looks elegant in person. Subtle enough to be classy, effective enough to actually lift. I feel confident whether I'm at the gym or grabbing coffee after.
-
Worried it would be see-through — it's not at all
I've been burned by thin leggings before. This fabric is thick, smooth and completely opaque. I did a full squat test and felt totally covered. The compression is real without being suffocating. Worth every penny.
-
I thought shapewear and workouts don't mix
I assumed tummy control would be too restrictive to exercise in. Wrong. I did a full HIIT class and never felt limited. The fabric stretches with you and snaps right back. My stomach looks flat and my waist looks tiny.
-
Compared it to my Skims and this wins hands down
Skims is great for lounging but does nothing for my shape at the gym. This actually sculpts. The waistband holds everything in and the scrunch makes my butt look incredible. Switching brands for activewear.
-
Thought one-piece would be annoying for bathroom breaks
Total non-issue. The fabric is so stretchy it takes seconds to get in and out of. I wore it all day — gym, errands, lunch — and never found it inconvenient. The comfort and the look make it completely worth it.
-
Wasn't expecting it to actually slim my thighs
I bought it for the waist control but the thigh compression surprised me. Everything looks smoother and more toned. The flare leg makes my legs look longer too. I've worn it four times this week already.

Frequently Asked Questions
Will it actually make a visible difference on my body, or is it just marketing?
Will it actually make a visible difference on my body, or is it just marketing?
Yes — and you'll see it the moment you put it on. The Scrunch Butt V-seam physically lifts and rounds your glutes, while the double-layer sculpting waistband compresses your midsection to visually flatten your tummy and cinch your waist. This is not a filter. This is not a promise. This is compression engineering you can feel and see in your mirror before you leave the house.
How do I know which size to order? I'm between two sizes.
How do I know which size to order? I'm between two sizes.
When in doubt, size down. The 4-way stretch seamless fabric is designed to hug your body, not squeeze it — it adapts to your shape and moves with you. If you're between a M and L, go with M for maximum sculpting effect. Check our Size Guide for exact measurements. And if it doesn't fit perfectly, our 30-day free return policy has you covered, no questions asked.
Is it comfortable enough to actually work out in, or will I feel restricted?
Is it comfortable enough to actually work out in, or will I feel restricted?
Completely. We designed the CurveSculpt™ for real movement — squats, lunges, HIIT, yoga, pilates. The seamless 4-way stretch fabric moves with your body and snaps right back to its shape. The waistband is firm but never painful. Hundreds of customers have worn it through full workout sessions without adjusting once. Sculpting and comfort are not opposites here.
Will the waistband roll down during my workout like every other legging I've tried?
Will the waistband roll down during my workout like every other legging I've tried?
Never. That's the entire point of the one-piece bodysuit design. Because the top and bottom are one connected garment, there is nothing to roll, shift or slide. The fabric stays exactly where it's supposed to — through every squat, every stretch, every stride. This is the problem the CurveSculpt™ was built to solve.
Is the fabric see-through when I bend over or squat?
Is the fabric see-through when I bend over or squat?
Not at all. The CurveSculpt™ uses a premium double-layer seamless fabric that is fully opaque at every angle. We squat-tested it. We bend-tested it. You can move with complete confidence. No awkward moments at the gym, guaranteed.
Will it still look and feel the same after washing?
Will it still look and feel the same after washing?
Yes. The fabric is engineered to maintain its shape, compression and elasticity wash after wash. Machine wash cold, gentle cycle, lay flat to dry — and it comes back looking brand new every time. No pilling, no fading, no stretching out. Customers regularly report wearing theirs 50+ times with zero loss of quality.
Is the open back too revealing? I'm not sure I'm comfortable with that.
Is the open back too revealing? I'm not sure I'm comfortable with that.
The open back is designed to be flattering, not exposing. The V-shaped cutout frames your back beautifully without revealing anything uncomfortable. Many of our customers who were initially hesitant say it became their favorite detail — it adds an elegant, confident touch that makes the piece feel special. You control how you wear it: pair it with a light jacket for a more covered look, or own it fully at the gym. Either way, you'll look incredible.
